. In Sweden January 21, 1944 a 1 The present invention relates to improvements in such brushing and cleaning apparatus which areprovided with a dust collecting receptacle, a removable coverfor said receptacle, and a handle for moving the brushing apparatus along the objeot to be cleaned, said handle being pivoted in a, vertical plane to the cover. i

The object of the inventionis to develop a simple and practical device for locking the cov'erto the dust collecting receptacle, when the appa; ratus is in operation, and which locking device maybe released and appliedautomatically solely by turning the handle in said vertical plane, when the cover. is to be removed or replaced respectively. According to the invention this is eflectedby providing the lockingdevice with releasing means cooperating with abutment means on the handle, which abutment means are adapted to engage said releasing meansto .unlock the locking device when the handle is turned, suitably upwardly, from its position of operation; and to apply the locking devicev when the handle is turned in the opposite direction.

According to preferred embodiments of the invention said locking device comprises-a displaceable locking member slidably mounted on top of the cover and engaging in the locking position a stationary locking member connected to the receptacle, suitably to the bottom of the receptacle, said displaceable locking member being. provided with suitable abutment means adapted to cooperate with the abutment means of the handle to bring said locking members out of and into engagement with one another respectively, when the. handle is turnedain the aforementioned way. I I

Other ieatures of the invention and its mode of action will be more closely set forth below in connection with a detailed description of two embodiments of the invention illustrated by way of example on the accompanying drawings.

Fig. 1 shows a vertical section, taken along the line I-,-I in Fig. 3, ofa brushing and cleaning apparatus providedwith an embodiment of the.

locking device according to the invention. Fig. 2 shows'a plan view of the locking device in Fig. 1. Fig. 3 shows a horizontal section through the dust collecting receptacle in Fig.1.

Fig. 4 shows a vertical section, taken along the line IV.IV in. Fig. 6, of a slightly modified brushing and cleaning apparatus provided with a sec- 6Claims (01. 15-4) In the einbodimentaccording to .Figs. l-3, l designates the suitably circular dust collecting re-f ceptacl of a brushing and cleaning apparatus, the receptacle being provided with a cover 2}. In

the bottom of the receptacle 4 rectangular open ings 3 are provided, in each of which a brush roller 4 is provided, which brush rollers are rotatably journalled in the receptacle with the roller axis 5 extending in the longitudinal direction of the opening. The openings 3 are inside the receptacle bordered by screens and pins 6 or the like projecting upwardly from the bottom.

The receptacle is further suitably dividedin four equally large compartments by means of partitions l which also serve as bearing supports for the interior ends of the axes of the brush rollers 4.. The bearings may consist of screws 8 or the like being screwed into the wall and partitions of the receptable. partitions 1 form at their central junction a rectangular hollow pin 9 which, when the cover 2 is placed on the receptacle, projects upwardly-through acorrespondingly shaped hole ill in the cover. 'Holes II are provided in the portion of the pin 9 protruding above the cover 2. A displaceable locking member 12 adapted as a plunger mayengage any one of the holes ll. Theplunger' l2 is'displaceably mounted in a bracket l3 which in some suitable manner is'secured to the top side of the cover 2; The plunger is actuated by a spring, I4 .placedfbeq tween 3. rear wall of the bracket l3 and a stop ring I5 on the plunger, whereby the spring will tend to press the plunger forwardly towards the pin 9. At its rear endthe plunger 12 is provided with an abutment member IS. The handle up:

the apparatus is pivoted to the cover 2 in a vertical plane about a pin I8 secured to a bracket 2| which is. fastened to the cover. The lower end of the handle H is provided with an abutment member. 19 adapted to make engagement with an upstanding projection 20 on the abutment member I6 when the handle is turned upwardly to the position indicated by chained lines in Fig.

i from the position of operation indicate'd' by full lines, and in doingso to pull the plunger out of engagement with the stationary locking mem-v ber 9. I The bracket 2| serving as a holder/and bearing for the handle I! is suitably also-adaptedas an abutment for the handle so that the latter may be turned only slightlypastthe vertical position.

This hasthe advantage that the cover 2 with the handle J1 may be placed on the floor or some. other support withoutttilting.

The receptacle 'lflis' around its circum-terencei receptacle, the handle I! is turned upwardly, for

example to the position indicated by chained lines. In this turning motion the abutment meme ber l9 at the lower end of the handle will engage the projection 20 of the abutment member I6 andpull the projection 20 with the member 16..

1 reached.

f 2,403,105 i c j r lines, whereby the lower end of the abutment 3| engages the edge 30 and pulls the locking meme ber 28 so far to the rear that the fore edge of the locking member 28 is wholly withdrawn from the groove 21 on the pin 23, whereupon the cover may be removed.

Also in this case the bracket M is so adapted that the handle ll may not be turned upwardly farther than'slightly pastthe vertical :position, 7

whereby the above mentioned advantages are 22 designates also in this casea protecting rubber ring.

'The invention is of course not limited only to 7 the above described and illustrated embodiments,

and the plunger l2 so far to the rear that the plunger I2 will be released from engagement with the pin 9, whereupon the cover 2 may belifted and removed from the" receptacle by 'means of the handler If the cover then is to be replaced} the'same has {to be lowered in such a way that the-pin '9 will protrude through the opening ill inthe cover. i

"f Then the handle I! is turned downwardly, whereby the projection is released so that the spring M displaces the plunger 20 into engagej V ment with one of the holes H in the pin 9.

described above, the cover may be removed and applied very comfortably; and solely by turning the handle in the one or the other direction,

In theembodiment' according to Figs. 4-6, the numerals designate corresponding parts as the same numerals in Figs. 1-3. Thus, l designates the dust collecting receptacle, 2 the cover, -3 the openings in the bottom of the receptacle, 4 the brush'rollers, 5 the axes of the brush r0l1ers,'and 6 the screens and pins projecting upwardly from the bottom, 'The receptacle isalso in this case divided in four compartments by partitions l, the' central junction of which is formed 'as a suit ablysolid pin 23. The brush rollers 4 are at the circumference of the receptacle journalled in bearings 24 and at their interior ends in bearings 25', which are supported by resilient arms 26. By this arrangement the removal and exchange of the brush rollers 4' is highly facilitated. The

pinj23 projects upwardly through a correspond ingly-shaped opening in the cover 2, and its part protruding above the cover is provided with a groove 21 that may run all around its circum- The groove 21 is adaptedto cooperate ference. with 'a plate-shaped locking member 28 slidably mounted on thetop side of the cover. The rear portion ofthe locking member is provided with an upwardly projecting abutment member 29 and an abutment edge 30. V

i In the same manner as in the first embodiment a handle I! is pivotally journalled; in a bracket 21 secured to the cover. An abutment member 3| is attached'to the lower end'of the handle IT;

The member 3| is so shaped that it will act like a'cam-disc when cooperating with the abutment 29. ,The lower free end of the abutment 3| will engage theabutment edge 30, when the handle is'turned to a substantially vertical position as indicated by chained lines in Fig. 4.

When the handle I! is in the position indicated by full lines, the fore edge of the plate-shaped locki g member 28 is kept insertedin the groove 21,011 the pin 23 due to thepressure of the abutment 3! against theabutment 29. If the conbut may be modified in various respects without departingfrom the idea of the invention.
